Don't get me wrong. I used transit for the majority of my career. Biked for as much of it. Love the ideas.
The VAST majority of people I would see have conversations about this seem to want others to take transit so that traffic is better for them in their car.
The vast majority of people I know have never lived where there was a transit system that would be useful for them. So of course they want other people to use it without planning on using it themselves. Give them a system that is worth using and they will use it (there will be a multi-year delay before they try/start using it though).
